Start by mixing flour, oil, water, egg, and 1/2 tsp salt together.
Knead the dough thoroughly and set aside.
The dough will have a more oily surface than a normal dough.
Chop the spinach a bit (but not into small pieces) and mix it with feta, oil, and lemon juice.
Mix everything well until it has a creamy and cohesive consistency.
Now take the dough and divide it into 5 lumps.
Then take one lump of dough and roll it out into a circle.
Make sure the dough is rolled relatively thin.
Then cover half of the circle with the filling and fold the other half of the dough over.
Seal the edges by pressing them thoroughly together.
Add oil to the pan and fry them on medium/high heat for about 7 minutes on each side.
Enjoy.
